Hello, thanks for writing in.
First, we times the two bases (5 x 3)(3)
The reason we set this up is because when finding the volume you need to times the two bases THEN the height.
5 x 3 = 15
15 x 3 = 45
Therefore, 35 is your volume.
80 - 20% = 64
Now we have to add the tax, so: 64 + 3% = $65.92
The answer should be $65.92.
I hope this helped,
good luck<3
Answer:
He needs 0.275 cups of orange juice to reach his estimates
Step-by-step explanation:
Patel estimates he needs 2 cups of orange juice for his family . He squeezed fresh juice from 5 different oranges and got the following quantities measured in cups.
4/17 cups, 3/10 cups , 9/20 cups, 3/11 cups and 7/15 cups.
Adding them together we will know the amount he got. Therefore,
4/17 + 3/10 + 9/20 + 3/11 + 7/15
(40 + 51)/170 + 9/20 + 3/11 + 7/15
91/170 + 9/20 + (45 + 77)/165
(1820 + 1530)/3400 + 122/165
3350/3400 + 122/165
0.98529411764 + 0.73939393939
1.72468805703
Patel got approximately 1.725 cups of orange juice . He will require 2 - 1.725 = 0.275 cups of orange juice to reach his estimates.
19.899 as an approximation
2 sqrt (99) = 6sqrt (11) exactly
Ab - c = 9 |subtract ab from both sides
- c = 9 - ab |change signs
c = -9 + ab
c = ab - 9
